arranged to receive and hold a large number .of the blanks o'r strips that are to be operated upon and in the preferred form of structure, this holder is so .arranged thatthestrips may all stand upon end. The holder contains a suitably operated feed device 11, which is arranged to feed the blanks one at the time up and away @om the remainder of the blanks.

A gate 12 isy'arranged in the path of the blank and, is constructed t0 revent the passage therethrough,` of more tlian oneblank at the time and said gate is operated and timed by suitable mechanism whereby the strips may follow each other in rapid succession.

Above -the gate 12 is located a horizontally extending feed'device 13, which is arranged to feed the blanks on to thepress 14. A second timing mechanism 15 is provided in con'- -nectio'n with the feeding device 13, which is arranged to hold back an4 oncoming blank until the one precedingr it has passed through the timer, thereby al o wing only one blank at the time to be operated upon by the press.

rovided for operating all of ysaid parts so lt atthey will operate together to feed the blanks from the stack one at the-time to the press.

We will now proceedto describe the several i parts in detail.

16-16 (see- Figs. 5 and 6), are standards secured to the lfloor by angle brackets 17, and toa 'platform 18, b angle brackets 19. The other end of the p atform is supported upon the body of the press 14, by angle brackets 20. The platform and standards "mounted in guide'grooves -ormed' between `hefstandards 16,and guide strips 26';` A-

cross-bar'27, connects the 'upper ends-of the bea 'ng plates 25,-which'bar1s pressed down- .Livar by springs 28, that engage adjustment f scrvs 29, which are' threaded in a stationary vafford a frame work for the operating parts.

' Turninf1r the screws 29 in cross-bar 30, secured upon the standards. the proper direction will tighten up the belt. j

Supplemental feed rollers 31, are j ournaled in brackets 32, mounted upon the slidable plates 25 and motion is given said rollers through a Abelt 33 andpulleys 34, 35. The rollers 31 areemployed wherever eXtra long blanks or strips are Ito be handled. A plurality of' backing pulleys 36, 37 are mounted between the two halvesof the belt 24, the pulleys 36 being journaled in bearings upon the standards, and the pulley 37 being jour naled in arms 38 adjustablysecured upon the standards. As shown the arms38 arepivotally connected to the standards so that by tilting said arms .the pulley 37 may be swung toward or away from the `stack of blanks. The purpose of this adjustment is to afford a close contact *between the friction belt 24 and the strips, as it frequently happens 'that they are somewhat warped or bowed, in which case the roller can be adjusted to accommodate the beltto the strips.

The blanks are supported in position to be operated upon by a frame like device, comprising a bar 39 supported upon standards I i 40,41, arms 42 and a follower device 43. `rllhe standard 41, is vertically adjustable, and

is held in place by a clamp 44, secured upon the fioor. By this arrangement the bar 39, can be given such an inclination as will facilitate movement'of the blanks, toward the feed belt. Thearms 42, hold the blank in place against the lateral movement and are adjustably mounted upon the standards by clamps 4 Thefo'llower 43, (see Fig. 1.2)

I comprises aber 4f6,"'a plurality of lingers 47,

pivoted to s/aidbana shifting bar 48, pivotallyconnected'to the'fingers at points eccentric with res ect to the pivotal connection between 'the Engers and bar 46, a supporting i rod 49 pivotallyA connected with the bar 46,

andlwith-'theplatform 18. The pivot pin of the finger 47 has secured to it a lever 50 which may be turnedtdfswing the fingers into operative position' 'to engage the blanks, or swing them behind the bar 46. `The bar 48, being lconnected to all'of the fingers, causes them toswing in unison. A plurality. of'

- hooks 51, are fastened upon the bar 46 and a wei ht 52, 'isconnected to" certain of said hoo s by ropes 53, 54'and pulleys 55, 56. This arrangement furnishes a follower device which holds the' stackl of blanks firmly in' contact with the friction belt 24. Above the belt 24,'is the tiineror gate device 12.

Referrin to Figs. 7, 8, 9 and 11, 57 and 58 are-,two p ates awhich furnish 'a restricted' passa e n each lgilank must pass in lits travel from the holder 10 to the feeding device 13. The

plate '57 is stationarily supported by a bar 59, which is secured to the standards 16, and the plate 58 is adjustably supported upon a each other in said feeding device.

way between them through which? bar 60 Which is also secured upon the standards 16. A set screw 61, is threaded in a bar 62, which is supported upon the bar 60, and said screw bears upon the plate 58. By turning the screw 61 in the proper` direction, the space between 'the two plates can be varied to conform to the thickness of the strips or blanks which are to pass through. In setting the plate 58 the screw 61 is turned. in the proper direction until the width of' the slit between the plates is approximately equal to the thickness of one blank or strip. The plate 58 has a fianged end 63, which guides' the adjacent blanks toward the slit.

vA movable timing stop 64, normally obstructs the upper end of the passage way betw en the plate 57, 58, and said stop is carrie by an arm 65, pivoted asl at 66 to the bar 562, a spring 67 acting to draw the stop down upon the plates. tively held down during a portion of' the time by means of a trigger or hook 68, pivoted to the bar 59 as at 69, which trigger is actuated by mechanism controlled by the passage of the blanks through the feeding device 13, and this mechanism is so timed that the trigger will release the stop only when a preceding blank has reached a predetermined position upon said feeding device, thereby avoiding the danger of piling the blanks upon To obtain an instantaneous and effective operation of the trigger we have arranged a simple, electrically operated device, for this purpose, which as shown comprises a magnet 70, an armature 71, and a circuit closing device comprising two bars 72, 77 and a Contact device 7,3, which circuit closing device is interposed in the circuit from the terminals of' the magnet 70 to the generator. The armature 71 is arranged to depress the end of the trigger 68, whenever the magnet is energized, thereby swinging the triggerupon its pivot and releasing thc stop 64, permitting the strip or blank to raise the stop, through the action` of' the friction belt 24, and to pass through the gate. The trigger 68 is returned to position for engagement with the stop 64, by a spring 74, which acts upon the trigger when the magnet is denergized and returns it to its operative positon. The end 75 of the trigger is beveled off so that Whenever 4the stop 64 is swung down ,alpen the plates, it will crowd the trigger back be# fore it strikes the plates, whereupon the trigger Will be returned by the spring 7 4 and engage the top of the stop.

The `contact bar 72, is insulated from the remainder of the device by blocks insulating material, andis placed in such a position that the b'laiiks or strips mustl necessarily pass over it, and the contact piece 73, is removably secured upon the bar 77. bars 72, 77 actL as terminals in the circuit and the contact piece 73 operates to open and The l hoivever, a blank or strip passes between the' linger and bar the 'ting-er isl raised by the blank and the circuit 1s broken. Thus the stop 0e', 1s positively locked down by the trigger 68 except Whenever no blank is traveling between the circuit making and breaking device. j

Adjacent to the gate 12, are journaled feed rollers 80, 84, 85 which engage the blanks and aid in advancing`them through thev gate.

Sprockets 81 and A82, mounted upon the shafts LL and 21a of the roller 8O and pulley 21 respectively and a sprocket chain S3 afford means lor revolving theroller 80. The rollers 84 are lrevolved' by sprockets 86, 87, and a chain 558i The rollers 85, .are journaled in arms 80 which are supportedupon the bar 00, and said. rollers are held in'frictional en*4 gagement with the rollers S4 by set screws 90, o

that are threaded in brackets 91 also secured upon the bar 60. located on the sides of the stop 64, and take hold of the blanks just as they emerge from the. gate 1:2. j

A guide strip 92, is secured to the platform 18, and is adapted to turn the blanksfrom a vertical position into 'a position to be acted upon by the leed devices 13. is formed with an opening 93, ata point, immediately above the gate 12, through which opening the blankpasses from the gate 12 tothe leed devices 13. The guide strips 9i bears a pressure roller 04, which bears upon the iced belt 95, that forms part of the feed device 13, and said rollerll, is positioned immediately' above a pulley 96,' which carries one end of the belt 95. The guide strip, 92`is preferably composed of spring material, andpresscs the roller 94,

down upon the belt 05, so that Whenever a blank is led in between said roller and belt, uit will be carried on toward the press, after 1t leaves the rollers SI1, S5. i j

trried by the )ulley 96 and by a drive p i, which is located adj acent tothe )ross and is belted to the press by a belt 98, Which-runs over pulleys 99 and 100, and an idler 101. The pulley 99 is mounted on the shalt which bears the pulley 97 and thel pulley 100, is mounted on the shaft 100L of the press 14.

A friction roller 103, bears upon the beltV 95, at a point immediately above the pulley 07, and said rpllcris'pressed don/'n upon the same by spring arms 10,4, the roller bein@ mounted upon a shaft 105,Wlnch rsjournaled The rollers 84, are` The platform in the :tree ends ci the arms 1041. Guides 106 are provided for directing the blanks in between the dies of the press, and said guides may be of any Well known form 4for guiding thev blanks to the dies.

Adjacent to-the rollers 103, isthe timer 15, which arrests the .movement of the blanks until the one preceding 4it has gone a certain distance beyond the roller 103, the Vobject beinlg to time the movement of the blanks so that they will follow earch other in rapid succession to the dies, and at the same time prevent more than one, at the time, from being operated upon by the dies. As shown the timer comprises a trigger 107, (see Figs. 4,1`4, 15 and 10) pivoted upon abracket 108 and; having arms 109, 110 one of which arranged to lie in the path of the 'blanks and to obstructtheir movement except at certain predetermined .timesjand the ,other of which 'is arranged to be "engaged byan arm'111a carried by the armature 111 of; a magnet 112, for bringing the other arm 10Q, out of the path ofthe blanks. The circuit to said magnet is-l controlled by contact pieces 113, 114, which form the terminals of the circuit. The contact piece 113, is located upon the reciprocating headk of the press, and the contact piece 1141 upon the frame of the device, and in position to contact with the contact piece 113 Whenever' the head reaches the bottom oi' its stroke. Hence every time that the contact pieces 113, 114, touch each other the magnet. 112 is energized and the trigger operated to release any blank which happens to be held back by the trigger. The contact piece 114, is however located below the plane of travel pass between the contact pieces 113, 114, the, result being that the magnet remains deenergized whenever a sheet is passing be tween the contact pieces. is held in operative position until the sheet has cleared the contact pieces whereupon contact will be made the next time that the head comes down, the magnet will be energized and the trigger operated to release the sheet which it is holding back. Guides 115, 116 are provided to guide the blank against the arm 109 of the trigger and a roller 1-17 is mounted just below the arm, over` which roller the blank rideson its Way to the press. A belt guide 118,- is placed under the upper bight of the belt 95, at a point adjacent to the guide 115, thereby bringing the belt into alinement vwith said guide. This. is for the purpose of directing the blanks against the trigger 107. The slmt @L of the press shalt 21a of theieeding bears a pulley 120, Whi is connected Witha "'pf the blanks so that they must necessarily Thus the trigger circuit is closed and the sto magnet is energized and the stop is free to be raised by the blank. The blank is then pushed through the gate by the feeding devices 11 until it reaches the belt 95' and roller 94 whereupon the belt takes hold and advances the blank to thetrigger 107. While the blank is passing under the contact piece 73 the magnet 70 is denergized and the sto 64, is locked down, but as soon as the blan has passed beyond the contact piece, 73 the y is unlocked, thereby permitting another b ank to follow the preceding one. There being no blank between the contact pieces 113, 114, the arm 109 is raised every time that the head of the press comes down, and as soonyas the blank reaches the trigger it passes on and through the press. The contact piece 73 should be set at such position upon'the bar 77 that the blanks will follow each other in quick 'suc-l cession, and it is highly desirable to have a blank reach the trigger just about the time 'that the preceding one is leaving or has left the trigger. The arm 109 of the trigger rests i upon the blank while the latter is passing under the trigger, but the/trigger immediately falls down into operative position as soon as the blank has assed by, thus preventing the following lank from reaching the press before the preceding one has been fully acted upon.

Among the important advantages of this device is its capacity for'feeding the sheets or blanks to the press the accuracy of the feed, and the adjustability for various sizes of blanks. It requires practically no attention exce t to keep the holder stocked with blanlis I lllhile only one form of construction has been shown Aand described 4it is not to be understood that we desire to limit ourselves to the recise details shown and described. Furt ermore the various parts may be yused in them entirely or may be used separately.
